For round cookies, swirl the warm cookies between a round pastry/cookie cutter while the cookies are still warm.
Cookies can be stored on the counter at room temperature for 3-4 days. They can also be frozen up to 1 month and just need to defrost at room temperature before eating. Cookies can also be stored in a closed container in the fridge and will keep up to 2 weeks, but it will make them less chewy.
If you are making smaller cookies, please adjust the cooking time to 8 minutes. For larger cookies you will need a longer cooking time.
